'''Beer''' is a crater on [[Mars (planet)|Mars]] named in honor of the German astronomer [[Wilhelm Beer]]. It is located at 351.8°E 14.5°S.
Beer and collaborator [[Johann Heinrich Mädler]] produced the first reasonably good maps of Mars in the early 1830s. When doing so, they selected a particular feature for the [[prime meridian]] of their charts. Their choice was strengthened when [[Giovanni Schiaparelli]] used the same location in 1877 for his more famous maps of Mars. The feature was later called ''Sinus Meridiani'' ("Middle Bay"), but following the landing of the [[NASA]] probe [[MER-B|MER-B ''Opportunity'']] in [[2004]] is perhaps better known as [[Meridiani Planum]].
Beer crater lies in the southwest of [[Meridiani Planum]], about 8° from the prime meridian and about 10° west from [[Mädler (crater on Mars)|Mädler crater]]. [[Schiaparelli (Martian crater)|Schiaparelli crater]] is also in the region.
